Solo version

In the United States, Canada, and the rest of the world outside of Europe, Bocelli's original solo version is by far the best known. Young Argentinian tenor Javier Fontana also recorded the song with approval. Bocelli usually performs Because We Believe, the part English/Italian version of the song, during concerts and events, although he sometimes performs "Ama Credi E Vai", the song with the Italian lyrics only, which he wrote himself.

Both "Ama Credi E Vai", and "Because We Believe", were released as part of the Amore album,^[1] January 31, 2006, which debuted at No. 3 on both the Billboard 200, and the Canadian albums charts.^[3][4]

On February 26, 2006, Bocelli performed the multilingual version of the song during the closing ceremony of the 2006 Winter Olympics, in Turin, before the flame was extinguished.^[1][2] While Bocelli was singing, 500 Italian brides entered the arena dressed in their wedding dresses, and carrying lighted lilies; they formed the "Dove of Peace" before the flame took its final breath.

In April 2006, Bocelli was a guest coach, along with David Foster, on Season 5 of American Idol, helping the finalists sing the week's themed songs, "Greatest Love Songs." He performed "Because We Believe" on the week's results show.^[5]

The song was also included in Bocelli's 2007, greatest hits album, The Best of Andrea Bocelli: Vivere.

On March 18, 2006, "Because We Believe" debuted at No. 39, on the U.S. Adult Contemporary chart, spending only one week on the chart.^[6]
